The length of the shell attains 75 mm. [2]

The shell is relatively thin, with a long, slender, and straight siphonal canal. The whorls are rounded, with the periphery featuring at most low spines, primarily on the apical spire whorls. The rest of the shell is sculpted with rounded axial ribs intersected by spiral cords, which are most prominent below the periphery. [2]

The shell is uniformly white, covered by a pale khaki-brown periostracum. [2]
